Advisory
Circular
Subject: Sport Parachuting
Date: 5/18/11
AC No: 105-2D
Initiated by: AFS-800
Change:
1. PURPOSE. This advisory circular (AC) provides suggestions to improve sport parachuting
safety and disseminates information to assist all parties associated with sport parachuting in
compliance with Title 14 of the Code of Federal Regulations (14 CFR) part 105. It also contains
information for jumpers and riggers on parachuting equipment, on-airport parachuting
operations, jump pilot training, aircraft maintenance programs, parachute rigging, and procedures
for Federal Aviation Administration (FAA) authorization for flight operations with a door
removed or modified.
2. CANCELLATION. This AC cancels AC 105-2C, Sport Parachute Jumping, dated 1/2/1991.
3. RELATED CFR PARTS AND PUBLICATIONS. The FAA’s primary responsibility with
respect to skydiving is the protection of air traffic and persons and property on the ground. This
is principally accomplished through part 105.
a. Title 14 CFR. This paragraph describes the 14 CFR parts that are of interest to skydivers,
parachute riggers, and jump aircraft pilots. They may be downloaded from the FAA’s Web site
at http://www.faa.gov. All FAA regulations, ACs, and other documents are also available for
download from the FAA’s Web site. Since the Federal regulations and other publications may be
amended at any time, skydivers, parachute riggers, and pilots should keep up with changes to
comply with current requirements.
(1) Title 14 CFR Part 65, Certification: Airmen Other Than Flight Crewmembers.
Subpart F concerns parachute riggers, their eligibility requirements, privileges, and performance
standards.
(2) Title 14 CFR Part 91, General Operating and Flight Rules. Parachute operators
and jump pilots must comply with all applicable sections of part 91.
(3) Title 14 CFR Part 119, Certification: Air Carriers and Commercial Operators,
Part 119, § 119.1(e)(6). When conducted within 25 statute miles of the airport of departure, the
parachute operation can be conducted as a commercial operation under part 91.
(4) Part 105, Parachute Operations. This part is especially important to parachutists, to
parachute riggers, and to the pilots who fly parachutists, since it contains regulations governing
intentional parachute jumping.
AC 105-2D
5/18/11
b. Technical Standard Order (TSO)-C23, Personnel Parachutes Assemblies. The
TSO-C23 series contains the minimum performance and safety requirements for parachutes.
New approved parachutes must be designed and tested to the current TSO standards. Parachutes
approved under earlier TSO standards may continue to be produced. The most current TSO-C23
document may be obtained from the FAA Web site, www.faa.gov.
c. Parachuting Symbols on Charts, Electronic Navigation Equipment, and Related
Publications. Having parachuting symbols on aeronautical charts, electronic navigation
equipment, and related publications helps alert pilots to the location of parachuting drop zones.
This allows pilots to be aware of drop zones and exercise caution in these areas. The FAA
Aeronautical Information Management (AJV-2) collects, stores, and distributes static parachute
jumping activities (PAJA) data for use in FAA publications, charts, and Navigation Databases
(NDB).
(1) Operators conducting parachute operations should report any additions, deletions, or
changes to static PAJA data to the FAA air traffic control (ATC) facility with jurisdiction over
the effected airspace. Operators should submit changes as outlined in part 105, § 105.15.
(2) ATC facilities that have jurisdiction over the affected airspace should report any
additions, deletions, or changes to static PAJA data to AJV-2. At a minimum, changes to be
reported should include location; distance and radial from the nearest Very high frequency
Omnidirectional Range (VOR) or Collocated VOR and TACAN (VORTAC); maximum altitude;
drop zone radius; day/time of use; and the ATC frequency. Submit static PAJA changes to the
National Flight Data Center Web site at http://nfdc.faa.gov. Use the “Aeronautical Chart
Changes” link to submit information.
4. BACKGROUND.
a. FAA-Recognized Aeronautical Activity. Sport parachuting (skydiving) continues to
increase in popularity and is an FAA-recognized aeronautical activity even though parachutists
are not certificated airmen. As an FAA-recognized aeronautical activity, regulations require
airports that have received FAA funding to accommodate this activity unless the FAA
determines that compatibility issues prohibit parachuting operations at a particular airport. See
the current edition of FAA Order 5190.6, FAA Airport Compliance Manual, appendix C,
paragraph 4, and appendix C, section 1, subparagraph 1.3.d.
b. Licensing, Instructor Rating, and Training. Sport parachuting has certain inherent
risks for all participants. Since 1946, the United States Parachute Association (USPA) and its
predecessor organizations (the National Parachute Jumpers and Riggers Association and the
Parachute Club of America) have developed skydiver licensing and instructor rating programs
the FAA recognizes as successful programs that have enhanced skydiver safety. The USPA has
also developed safety guidelines and standard practices known as the Basic Safety Requirements
(BSR). The USPA has assembled these procedures, training programs, and BSRs into their
Skydiver’s Information Manual. The FAA recommends that all beginning parachutists obtain
formal training conducted in accordance with the USPA BSRs or by training programs from
other similar organizations. Current sport parachute student training programs offered by the
USPA can be found on their Web site at http://www.uspa.org.
Page 2
Par 3
5/18/11
AC 105-2D
c. The Parachute Industry Association (PIA). Parachute equipment and accessories must
be used with care. The PIA is an international trade association founded in 1976, devoted to the
advancement and safety of parachutes and parachuting activities. Its membership is comprised of
equipment manufacturers, materials suppliers, parachute riggers, government and military
agencies, and other industry professionals. The PIA creates, publishes, and maintains materials,
technical, and certification standards relating to parachutes, located on their Web site at
http://www.pia.com.
d. Safety Recommendations. In the revision process of this AC, the FAA took into
consideration the safety recommendations of the National Transportation Safety Board (NTSB)
and comments solicited from the parachuting industry members, the USPA, and the PIA.
5. SKYDIVER SAFETY.
a. BSRs. The USPA developed basic safety standards and information for skydiving
activities called BSRs. These standards and information are for training, checking equipment,
and conducting a wide variety of sport parachuting activities. While not approved by the FAA,
the BSRs are considered industry best practices and are widely accepted for use by individuals
and parachute centers. The BSRs may be obtained from The United States Parachute
Association, 5401 Southpoint Centre Boulevard, Fredericksburg, Virginia 22407. The phone
number is 540-604-9740 and the USPA Web site is http://www.uspa.org. The FAA encourages
skydivers to use facilities that conduct their operations in accordance with the USPA BSRs or
other similar skydiving association best practices.
b. Medical Certificates. While the regulations do not require an FAA medical certification,
the FAA urges prospective skydivers to receive a physical examination prior to their first jump.
The skydiver should inform the physician of the purpose of the examination.
c. First-Jump Training Methods. The skydiving industry has developed various methods
of first-jump instruction. The FAA recommends that beginning skydivers seek instruction from
instructors that have met the qualifications set forth by the USPA or other similar skydiving
associations.
d. Safety Devices and Equipment.
(1) Deployment Assist Device. Federal regulations require that all persons making a
parachute jump, with a static line attached to the aircraft and the main parachute, use an assist
device to aid the pilot chute in performing its function. An assist device is also required if no
pilot chute is used in direct deployment of a round, main parachute canopy. The regulations do
not require an assist device for direct deployment of a ram-air main parachute canopy.
(2) Automatic Activation Device (AAD). An AAD is a self-contained mechanical or
electro-mechanical backup device attached to the parachute container that automatically releases
the parachute closing system when it meets specific parameters, such as exceeding a specific
vertical velocity and being at or below a specific altitude. An AAD does not physically open the
parachute container or deploy the canopy, but rather initiates the container opening by pulling
the ripcord pin or by cutting the container closing loop, allowing the canopy to deploy in a
Par 4
Page 3
AC 105-2D
5/18/11
similar manner as when pulling the ripcord manually. Generally, AADs are installed on the
reserve parachute.
(a) The FAA requires that all tandem parachutes have an AAD installed on the
reserve parachute. Industry associations, such as the USPA, require their affiliated skydiving
schools and clubs to provide and/or require the use of an AAD for all student or unlicensed
skydivers.
(b) The FAA has not established Minimum Operational Performance Standards
(MOPS) or a TSO for AADs. Therefore, the FAA recommends that anyone using an AAD
review manufacturer’s reports conforming to the PIA standard TS-120, AAD Design and Testing
Report Format, or any independent third-party reports, in order to make an educated decision
prior to the use of any particular make or model AAD. The FAA recommends that jumpers using
AADs to satisfy the requirements set forth in part 105 purchase them from manufacturers that
provide such reports, which provide a means to determine device airworthiness.
(c) Users of AADs should be aware of the device’s level of reliability and its
operating limitations, be knowledgeable about the various parameters of the device, and be
trained on the specific use and setting for the particular AAD. Users should be well informed
about the use of the AAD and have access to the manufacturer’s instructions.
(d) Furthermore, users should understand that AADs are strictly backup devices and
are not intended to replace training or timely manual execution of emergency procedures. AADs
may or may not initiate reserve parachute deployment at a sufficient altitude, depending upon
various combinations of circumstances.
(e) Jumpers should make a pre-jump check using the manufacturer’s recommended
procedures for proper setting, arming, and operational status verification to ensure the proper
functioning of the AAD. This pre-jump check is usually made prior to boarding the aircraft to
ensure that it is set at the proper altitude and under current weather conditions to aid in accuracy.
This is especially important when using an AAD that has selectable or adjustable activation
settings, or when the intended landing area is at an elevation different from that of the departure
airfield.
(f) AADs may have selectable or adjustable altitude activation settings. Some AADs
are preset for the intended type of operation (i.e., Tandem, Student, Expert, etc.), while others
may be user-selectable. Caution should be exercised to ensure that the appropriate model,
version, settings, or all three are used for the particular type of equipment and jump.
(g) Body position and other factors may cause a delay in the actual parachute opening
altitude, which is another reason why such devices should be used only as a backup to manually
deploying the reserve parachute. When the situation requires the use of the reserve parachute, the
jumper should always manually pull the reserve ripcord using the established procedures for
reserve deployment before ever reaching AAD activation altitude. The procedures for
deployment of the reserve parachute are usually the same whether an AAD is installed or not.
(h) Report any malfunctions or activations of the AAD to the AAD manufacturer.

AC 105-2D
e. Weather. Strong or gusty winds can be dangerous, especially to student jumpers. The
USPA recommends that the maximum winds for students be 14 miles per hour (mph) for ram-air
reserves and 10 mph for round reserves. In addition, skydivers and pilots should ensure that there
is adequate ceiling and visibility to maintain the required weather minimums.
f. Parachute Landing Areas. The FAA recommends that areas used as parachute landing
areas remain unobstructed, with sufficient minimum radial distances to the nearest hazard. The
USPA has defined such distances and hazards in their BSRs.
g. Water Safety Equipment. Flotation gear should be worn whenever the intended exit
point, or landing point, of a skydiver is within 1 mile of an open body of water.
h. Advanced Parachuting. Many of the safety suggestions presented in this AC are
intended primarily for the student parachutist. All student jumps should be made in a controlled
training environment. Individual experience and judgment dictate what additional training should
be obtained before undertaking more advanced parachuting activities. All parachutists should
acquire experience and training before using unfamiliar or high-performance equipment.
6. PARACHUTE OPERATIONS ONTO AIRPORTS.
a. Stipulations for Landing at or Flying over an Airport. Most parachute operations take
place on airports, including having the parachute landing area located on the airport property.
Section 105.23 requires approval from airport management prior to skydiving onto any airport.
However, § 105.23(c) allows a parachutist to drift over an airport with an open parachute without
airport management approval as long as the parachutist remains at least 2,000 feet above that
airport’s traffic pattern. (Airport traffic patterns are generally 1,000–1,500 feet above ground
level (AGL).)
b. Additional Aviation Activities. A large number of airports that accommodate parachute
operations also have different kinds of aviation activities taking place simultaneously, including
flight training, glider and helicopter operations, helicopter emergency medical services,
sightseeing operations, and aerobatic practice over or in the immediate vicinity of the airport.
Many airports accommodate a large volume of transient traffic during skydiving operations.
c. Shared-Facility Airports. The FAA recommends that shared-facility airports have
operating procedures so that each activity can operate safely by knowing the procedures for each
of the other activities. Representatives of each type of activity can operate more effectively by
knowing the procedures for each of the other activities. Representatives of each type of airport
user group should develop procedures specific to their activity and share these procedures with
other user groups. It is the airport management’s responsibility to ensure that airport policies and
procedures are kept current. This can be accomplished via regularly scheduled meetings with all
airport user groups.
(1) Traffic Patterns. With a minimum parachute opening altitude of 2,000 feet above the
ground (and most parachutists open much higher), parachutes are nearly always open 800 feet or
more above the traffic pattern altitude for any airport. Descending slowly and easy to visually
acquire, parachutists and pilots have a shared responsibility to see and avoid each other. Often,
Par 5
Page 5
AC 105-2D
5/18/11
procedures can be implemented that reduce the potential for parachutists and pilots in a traffic
pattern to be in proximity.
(2) Parachute Landings on Airports. Airports may designate suitable parachute landing
areas. While skydivers attempt to land in such areas, at times there may be inadvertent landings
in other grass or hard-surfaced areas. This could include landings on runways, taxiways, and
other hard-surfaced areas. Areas such as runways, taxiways, clearways, and obstacle-free zones
are not prohibited areas but should not be designated as a primary landing area and should be
vacated as soon as practical. Flying a parachute over runways at low altitudes should be avoided
where possible. The FAA recommends that airport management work with parachute operators
to develop standard operating procedures (SOP) for activities conducted by parachutists.
d. Additional Information. For additional information, see the current editions of
AC 150/5190-7, Minimum Standards for Commercial Aeronautical Activities, and FAA
Order 5190.6.
7. JUMP AIRCRAFT MAINTENANCE AND JUMP PILOTS. Whenever flights are
offered for compensation or hire, the flight is considered a commercial operation under part 91
and Federal regulations require:
a. Aircraft Inspections. Aircraft must be maintained in accordance with part 91, § 91.409.
In most applications, operators must comply with one of four inspection programs:
(1) Section 91.409(a) and (b), annual and 100-hour inspection programs;
(2) Section 91.409(d), progressive inspection program;
(3) Section 91.409(f)(3), manufacturer’s inspection program; or
(4) Section 91.409(f)(4), approved inspection program.
b. Additional Information on Acceptable Maintenance Programs. Anyone conducting
parachuting operations should contact his or her local FAA Flight Standards District Office
(FSDO) for additional information on acceptable maintenance programs. Reviewing aircraft
maintenance records can be simplified by the use of an aircraft status sheet (Figure 1, FAA
Aircraft Status Inspection List Example).

8. PILOT RESPONSIBILITIES. The pilot in command (PIC) must adhere to all regulations
applicable to the operation conducted. This includes, but is not limited to, the following:
a. Pilot Certification Experience and Operating Requirements. The PIC is responsible
for meeting the certification, proficiency, operating, and experience requirements of, but not
limited to, 14 CFR parts 61, 91, and 105.
b. Jump Pilot Training and Check Out. Pilots conducting flight operations for
compensation or hire are required to possess a Commercial Pilot Certificate with the appropriate
ratings for the aircraft being flown and must have a current Class 2 medical certificate or
equivalent. Any questions regarding these requirements should be directed to the local FAA
FSDO for consideration. The FAA recommends that pilots flying aircraft for the purpose of sport
parachuting have appropriate training and have received a thorough checkout in the jump aircraft
to include, but not limited to:
(1) Ground Training.
(a) Aircraft limitations.
(b) Weight and Balance (W&B).
Par 7
Page 7
AC 105-2D
5/18/11
1. Takeoff computations.
2. Weight shift in flight procedures for exiting jumpers.
3. Landing configuration.
(c) Low-speed operations for jump runs.
1. Maneuvering at minimum speed.
2. Opening and closing jump door, if applicable.
3. Stall recognition and recovery.
(d) Emergency procedures.
1. Standard aircraft emergencies.
2. Emergencies caused by jump activities.
3. Bail-out procedures.
(e) Determining aircraft airworthiness.
1. Maintenance requirements and procedures.
2. Aircraft status log (Figure 1).
3. Minimum equipment list (MEL), if applicable.
4. Logging maintenance discrepancies.
(f) Ensure that all parachutes have been packed within 180 days.
(g) Familiarity of jump area.
(2) Flight Training.
(a) Takeoffs and landings with representative loads.
(b) Center of gravity (CG) shift with unloading of jumpers.
(c) Stall-spin prevention and recovery.
(d) Tail strike prevention for jumpers.
NOTE: The potential exists for jumpers to strike the tail of many aircraft
when exiting the airplane in flight. Pilots should brief the jumpers on tail
strike avoidance procedures. No exits should be made from any airplane
Page 8
Par 8
5/18/11
AC 105-2D
unless the airplane is level flight with reduced power and airspeed and flaps,
if necessary. Jumpers should not exit the airplane in a climb configuration.
c. W&B Procedures. The PIC is solely responsible for assuring that the aircraft being
flown is properly loaded and operated so that it stays within gross weight and CG limitations.
The PIC must ensure that the aircraft is operated within the aircraft W&B limitations. Additional
aircraft station position information (loading schedule) should be obtained by the PIC for future
W&B computations. The PIC is also responsible for reviewing these records and the flight
manual to be familiar with an aircraft’s W&B procedures and flight characteristics.
d. Computing W&B. The PIC must include the following factors:
(1) The maximum allowable gross weight and the CG limitations.
(2) The currently configured empty weight and CG location.
(3) The weight and CG location prior to each flight.
(4) The weight and location of jumpers during each phase of the flight in order to assure
that the aircraft stays within CG limits. The PIC must remain aware of CG shifts and their effects
on aircraft controllability and stability as jumpers move into position for exiting the aircraft and
as they exit.
e. Operational Requirements. The PIC is solely responsible for the operational
requirements of parts 91 and 105 to include the special operating limitations and placards
required for flight with the door open or removed.
f. Suitable Placards. Placards should be located in the aircraft to help the pilot inform
jumpers of the maximum approved loading and weight distribution. These placards should be
located where they will be seen by anyone boarding the aircraft and should clearly show the
maximum approved seating capacity and the load distribution. However, since many jumpers are
not familiar with aircraft W&B procedures, it remains the PIC’s responsibility to ensure that
proper W&B is maintained throughout all parachuting operations.
g. Seatbelts and Approved Loading. Section 91.107 permits persons aboard an aircraft for
the purpose of participating in sport parachuting activities to use the floor of the aircraft for a
seat. However, among jump aircraft there are a wide variety of seats, benches, troop seats, and
floor seating arrangements. In all cases, seatbelts must be provided for each person and their
installation must be approved. See Appendix 3 for additional information describing seat and
restraint system configurations. The maximum number of skydivers is determined by that
aircraft’s W&B limitations, as long as there is a seatbelt or restraint for each skydiver. The
approved number of skydivers that can be carried for parachute operations will most commonly
be found on an FAA Form 337, Major Repair and Alteration (Airframe, Powerplant, Propeller,
or Appliance), used for field approvals, or an aircraft Supplemental Type Certificate (STC).
h. Oxygen. Jump pilots must use oxygen when flying above 14,000 feet mean sea level
(MSL). Skydivers must use oxygen when the jump plane is above 15,000 feet MSL. Above
25,000 feet MSL, pressure-demand oxygen systems should be used. High altitude jumps should
Par 8
Page 9
AC 105-2D
5/18/11
be made only after first becoming familiar with the problems and hazards created by low
temperatures, lack of oxygen, and the various types of oxygen equipment. High altitude jumps
should not be attempted without an adequate supply of breathing oxygen.
i. Altitude Reporting. Report all altitudes to ATC in feet above MSL.
9. PARACHUTE OPERATIONS IN DESIGNATED AIRSPACE. Section 105.25 contains
information on the ATC authorization and notification process.
a. Parachute Operations Restrictions. No person may conduct a parachute operation, and
no PIC of an aircraft may allow a parachute operation to be conducted from that aircraft:
(1) Over or within a restricted area or prohibited area, unless the controlling agency of
the area concerned has authorized that parachute operation;
(2) Within or into a Class A, B, C, or D airspace area without, or in violation of the
requirements of, an ATC authorization issued under § 105.25; or
(3) Except as provided in subparagraph 9c and subparagraph 9d, within or into a Class E
or G airspace area, unless the ATC facility that has jurisdiction over the airspace at the first
intended exit altitude is notified of the parachute operation no earlier than 24 hours before and no
later than 1 hour before the parachute operation begins.
b. Request for a Parachute Operation Authorization or Notification. Each request for a
parachute operation authorization or notification required under this section must be submitted to
the ATC facility that has jurisdiction over the airspace at the first intended exit altitude and must
include the information prescribed by § 105.15(a).
c. Notification of Parachute Operations. For the purposes of subparagraph 9a(3), ATC
facilities may accept a written notification from an organization that conducts parachute
operations and lists the scheduled series of parachute operations to be conducted over a stated
period of time not longer than 12 calendar-months. The notification must contain the information
prescribed by § 105.15(a); identify the responsible persons associated with that parachute
operation; and be submitted at least 15 days, but not more than 30 days, before the parachute
operation begins. The FAA may revoke the acceptance of the notification for any failure of the
organization conducting the parachute operations to comply with its requirements.
d. Armed Force. Subaragraph 9a(3) does not apply to a parachute operation conducted by a
member of a Department of Defense (DOD) Armed Force within a restricted area that extends
upward from the surface when that area is under the control of the DOD Armed Force.
10. JUMPS OVER AND INTO CONGESTED AREAS AND OPEN-AIR ASSEMBLIES
OF PERSONS.
a. Off-Airport Jumps. A skydiver may make parachute jumps away from the usual
on-airport parachute school, club, or center location, as long as landowner permission is obtained
for the off-airport location.
Page 10
Par 8
5/18/11
AC 105-2D
b. Certificate of Authorization (COA). Section 105.21(b) requires an FAA COA to
conduct a parachute operation over or into a congested area of a city, town, or settlement, or an
open-air assembly of persons. This COA must be obtained from the FAA FSDO that has
jurisdiction over the site where the jump is proposed by submitting an application,
FAA Form 7711-2, Certificate of Waiver or Authorization Application. FAA Form 7711-2 and
information on filling out this form can be obtained from your local FSDO or downloaded from
the following Web site: http://www.faa.gov/about/initiatives/airshow. An application for a COA
should be submitted at least 10 working-days in advance of the intended jump date to allow time
for processing. Approval or denial of the application must be completed within 5 working-days
of receipt by the FSDO.
11. REQUIRED INFORMATION.
a. COA-Required Information. A person submitting a request for a COA is required to
submit the information found in § 105.15:
(1) The date and time the parachute operation will begin.
(2) The radius of the drop zone around the target expressed in nautical miles (NM).
(3) The location of the center of the drop zone in relation to:
(a) The nearest VOR facility in terms of the VOR radial of its location and its
distance in NM from the VOR facility when that facility is 30 NM or less from the drop zone
target; or
(b) The nearest airport, town, or city depicted on the appropriate Coast and Geodetic
Survey World Aeronautical Chart or Sectional Aeronautical Chart, when the nearest VOR
facility is more than 30 NM from the drop zone target.
(4) Each altitude above MSL at which the aircraft will be operated when parachutists or
objects exit the aircraft.
(5) The duration of the intended parachute operation.
(6) The name, address, and telephone number of the person who requests the
authorization or gives notice of the parachute operation.
(7) The registration number of the aircraft to be used.
(8) The name of the ATC facility with jurisdiction over the airspace at the first intended
exit altitude to be used for the parachute operation.
b. Available on Request. Each holder of a COA issued under § 105.21(b) must present that
certificate for inspection upon the request of the Administrator or any Federal, State, or local
official.
Par 10
Page 11
AC 105-2D
5/18/11
c. Postponed or Canceled Operation. Each person requesting an authorization under
§ 105.21(b) must promptly notify the ATC facility that has jurisdiction over the affected airspace
if the proposed or scheduled parachute operation is canceled or postponed.
d. Authorization and Notification Requirements. Whether regulations require verbal or
written authorization, or a COA (FAA Form 7711-1), for a parachute operation depends upon the
type of airspace involved and the area where the parachutist intends to land. The airspace and
landing area will determine the requirements. Parachutists and pilots can use Appendix 1 to
determine what authorization or notification requirements are necessary for various types of
jumps. The FAA recommends that anyone establishing a permanent drop zone or a temporary
jump site contact the ATC facilities nearest the site as early as possible. ATC personnel are in the
best position to provide information on arrival and departure routes, airspace classifications, and
other airspace operations that may affect the safe and efficient flow of a parachuting operation. If
you are uncertain of the requirements after looking at Appendix 1, contact your local FSDO
and/or ATC facility for additional information.
12. PARACHUTE EXHIBITION LANDING AREAS. The FAA requires the following size
areas when issuing a COA for parachuting demonstrations into off-airport locations:
a. Open Field. No less than 500,000 square feet that will accommodate landing no closer
than 100 feet from spectators.
b. Level I. An open area that will accommodate a landing area no smaller than
250,000 square feet and which will accommodate landing no closer than 50 feet from spectators.
c. Level II. The level II landing area must be large enough in any direction to accommodate
jumpers landing no closer than 15 feet from spectators.
d. Stadium. A level II landing area smaller than 150 yards in length by 80 yards in width
and bounded on two sides or more by bleachers, walls, or buildings in excess of 50 feet high.
NOTE: In addition to landing area size requirements, the FAA also imposes
qualification and currency requirements found in the Parachuting Special
Provisions listed in FAA Order 8900.1, Flight Standards Information
Management System (FSIMS), located at http://fsims.faa.gov. Parachuting
demonstrations that seek relief from any requirement listed in these special
provisions must have a letter of approval from the FAA General Aviation
and Commercial Division (AFS-800), Federal Aviation Administration,
Flight Standards Service, Room 821, 800 Independence Avenue, S.W.,
Washington, D.C. 20591 (e.g., airborne reenactment by civilians for reduced
experience or lower opening altitudes).

13. PARACHUTE EQUIPMENT RULES.
a. Parachute. Title 14 CFR part 1, § 1.1 defines a parachute as a device used or intended to
be used to retard the fall of a body or object through the air. For the purposes of this AC, a
parachute assembly normally, but not exclusively, consists of the following major components: a
canopy, a deployment device, a pilot chute and/or drogue, risers, a stowage container, a harness,
and an actuation device (ripcord). There are, of course, some lesser parts associated with these
major components such as connector links, bridles, and hardware. The term “pack” when used in
this AC refers to the complete harness-container system, including the main parachute container,
plus the reserve parachute and associated components. Except for a reserve static line
(if installed), it does not include the main canopy, main risers, or components that depart with the
main canopy if it is jettisoned. If the design of the reserve stowage container is to be assembled
to a harness by a parachutist or rigger (such as a chest-type system or some pilot emergency
systems), the term “pack” refers to the parachute assembly less the harness.
b. Parachute Harness. Section 105.43 requires a solo parachutist making an intentional
jump wearing a single-harness dual-pack parachute to have at least one main parachute and one
approved reserve parachute. For tandem jumps, the parachute system defined in § 105.3 includes
a main parachute, a reserve parachute, a harness and dual parachute container, an AAD, and a
forward harness for a passenger parachutist. For both solo and tandem parachutists, the harnesses
(including the forward harness of a tandem system), and reserve parachute packs must be
approved types, but the main parachutes do not need approval. The following are examples of
approved parachutes as defined in § 105.3:
(1) Parachutes manufactured under TSO-C23. This TSO prescribes the minimum
performance and quality assurance (QA) standards for a parachute that is carried aboard civil
aircraft or by skydivers for emergency use. The manufacturer must meet these standards before
labeling its parachute or components as complying with the TSO.
(2) Military personnel-carrying parachutes (other than high altitude, high speed, or
ejection kinds) identified by military drawing number, military order number, or any other
military designation or specification. These parachutes are often referred to as demilitarized or
military surplus parachutes.
c. Assembly of Major Components. The assembly or mating of approved parachute
components from different manufacturers may be made by a certificated, appropriately rated
parachute rigger in accordance with the parachute manufacturer’s instructions and without
further authorization by the manufacturer or the FAA. Specifically, when various parachute
components are interchanged, the parachute rigger should follow the canopy manufacturer’s
instructions as well as the parachute container manufacturer’s instructions. However, the
container manufacturer’s instructions take precedence when there is a conflict between the two.
(1) Assembled parachute components must be compatible. Each component of the
resulting assembly must function properly and may not interfere with the operation of the other
components. For example:
Par 13
Page 13
AC 105-2D
5/18/11
(a) Do not install a canopy of lesser or greater pack volume than the intended design
criteria for the specific size of container, since it could adversely affect the proper functioning of
the entire parachute assembly. Likewise, do not install a high-volume canopy into a low-volume
container.
(b) A TSO’d canopy may be assembled with a demilitarized harness, or vice versa, as
long as the assembled components comply with the safety standard of the original design.
(2) Any questions about the operation of the assembly should be resolved by actual tests
by the rigger to make certain the parachute is safe for emergency use.
(3) For a single-harness parachute system, the strength of the harness must always be
equal to or greater than the maximum force generated by the canopy during certification tests.
The rigger who assembles the system should record these limits in a place accessible to the user
when he or she dons the assembly. For tandem systems, there may be additional limits for each
harness. Some manufacturers may also specify minimum weights or speeds for safe operation.
(a) In the case where the harness is certified under the TSO-C23b “Standard”
category, and the canopy is certified under TSO-C23b and TSO-C23d, the system is limited to
the performance limitations of the canopy and may be determined by comparing the placarded
force generated on the canopy to the 5,000-pound force capability of the harness. If the canopy is
placarded at or above the 5,000-pound level, then the system is considered “unlimited.”
(b) In the case where the harness is certified under the TSO-C23b “Low Speed”
category, and the canopy is certified under TSO-C23b and TSO-C23d, the system is limited to
the placarded performance limitations of the canopy or the structural limitation of the harness
(3,000 pounds), whichever is lower.
(c) TSO-C23c components may only be used in situations where they are mated with
the same components with which they were originally certificated, unless they are
retro-placarded by a Service Bulletin (SB) or other notification identifying the maximum forces
generated during testing. These forces could then be applied as in TSO-C23c.
(d) TSO-C23d components may be mixed or matched with other TSO-C23d
components by comparing the harness forces placard to the canopy force placard and certifying
the weight and speed of the lower of the two placards.
d. AAD Installation. The FAA approves the installation (addition of pockets, channels,
guides, etc., required for the AAD to be assembled in the parachute container) of each
make/model AAD as part of the paperwork that is submitted by the parachute manufacturer
during the TSO approval. Complete installation in consultation with, and with the approval of,
the AAD manufacturer. The retrofit installation, or installation of a make or model AAD other
than those specifically approved for a particular TSO or Military Specifications
(MIL-SPEC)-approved parachute, constitutes an alteration to that parachute (see paragraph 16).
e. Instructions for Maintenance, Repair, or Alteration of Specific Parachutes. These
instructions may be available by contacting manufacturers. Many manufacturers provide their
Page 14
Par 13
5/18/11
AC 105-2D
manuals online through their Web sites. The PIA Web site, http://www.pia.com, provides a good
starting point for searches.
f. Parachutist’s Handling of Equipment. The user of a parachute system may perform
simple assembly and disassembly operations necessary for transportation, handling, or storage
between periods of use if the parachute’s design simplifies such assembly and disassembly
without the use of complex operations.
g. Removal of Pilot Chute. A certificated senior or master parachute rigger may remove
the pilot chute from a front-mounted (e.g., chest-type) reserve parachute if the canopy does not
use a diaper, bag, or other deployment device. When done, the parachute must be plainly
marked, “PILOT CHUTE REMOVED. This parachute may be used for intentional jumping
only.”
h. Extra Equipment. The FAA does not consider the attachment of an instrument panel,
knife sheath, or other material to the exterior of the parachute assembly an alteration. If attaching
any extra equipment, take care not to impair the functional design of the system.
14. PARACHUTE PACKING.
a. Reserve Parachutes.
(1) The reserve parachute must be packed by a certificated and appropriately rated
parachute rigger (see § 105.43(b).) See part 65, § 65.125(a)(2) and (b)(2) for supervision of other
persons.
(2) Visiting foreign parachutists jumping parachute systems not approved by the FAA
must have their reserve parachutes packed by someone acceptable to the foreign parachutist’s
civil aviation authority (CAA) or by an FAA-certificated rigger. (See § 105.49(a)(4)(ii).)
(3) The reserve parachute must be packed within 180 days before the date of use if the
parachute system is made of materials substantially resistant to mold, mildew, or other rotting
agents, or within 60 days of the date of use otherwise. (See § 105.43(b).)
(4) AADs must be maintained in accordance with the AAD manufacturer’s instructions
and service requirements. Since when a rigger packs a reserve parachute the rigger is only
certifying that it meets all safety requirements on the day it is packed, riggers should note any
maintenance or battery replacement due date(s) on the packing data card so that users are able to
determine AAD airworthiness and ensure conformance to the regulations. (See §§ 105.43(c) and
105.45(b)(3).) AADs are to be installed as per the parachute manufacturer’s instructions.
(5) Only the rigger who did the packing, and whose seal is removed to permit scheduled
or unscheduled maintenance or repairs to the reserve container, may open, re-close, and re-seal it
(for example, AAD service or closing loop adjustment) within the 180-day or 60-day period in
subparagraph 14a(3).
b. Main Parachutes. Main parachutes must be packed within 180 days before the date of
use. They may be packed by any certificated parachute rigger or a person working under the
Par 13
Page 15
AC 105-2D
5/18/11
direct supervision of a certificated parachute rigger. The person making the next jump
(including a tandem parachutist in command, but not the passenger parachutist) may also pack
the main parachute. (See § 65.111(b).)
15. PARACHUTE REPAIRS.
a. Major Repairs. A major repair as defined in § 1.1 is a repair that if improperly done
might appreciably affect airworthiness.
b. Minor Repair. A minor repair is a repair other than a major repair.
c. Major or Minor Repair Determination. When there is a question about whether a
particular repair is major or minor, follow the manufacturer’s instructions.
(1) If the procedure calls for a master rigger, it should be considered a major repair. If the
procedure allows for a senior rigger, it should be considered a minor repair. The same kind of
repair may be classed as major or minor depending on size or proximity to key structural
components. For example, a basic patch may be a minor repair if it is small and away from
seams, but may be a major repair if it is large or adjacent to a seam.
(2) The riggers must be aware that any repair on a TSO canopy is a major repair, while
replacement of a suspension line on a non-TSO’d main canopy is generally considered a minor
repair, even if the identical technique is required for both replacements.
(3) Major repairs may be made only by an appropriately rated master rigger or a
manufacturer of approved parachute components. The manufacturer may designate certain
repairs to be done only by the manufacturer or the manufacturer’s designee.
16. PARACHUTE ALTERATIONS.
a. Configuration. Alterations are changes to a parachute system configuration that have not
been approved by the manufacturer or the manufacturer’s supervising FAA ACO. Examples
include removing a deployment device from a reserve canopy, adding harness fittings to permit
attaching an additional canopy, using non-standard repair materials or techniques, or installation
of a specific make/model AAD, when the manufacturer has not authorized such changes.
Changes that result in an approved configuration are considered repairs (see paragraph 15).
b. Approval. An alteration to an approved parachute system must be done in accordance
with approved manuals and specifications and only by those with specific authorization to
perform that alteration. Specific approval is not needed for the method of altering a non-TSO’d
main parachute canopy. A person seeking authorization to alter an approved parachute system
should proceed as follows:
(1) A person qualified to alter a parachute (as listed below) should contact his or her local
FAA FSDO inspector to discuss the proposed alteration. The applicant should be prepared to
show the inspector the nature of the alteration by using a sample assembly, sketch, or drawing
and be prepared to discuss the nature of the tests that will be needed to show that the altered
parachute meets all applicable requirements.
Page 16
Par 14
5/18/11
AC 105-2D
(2) The inspector will review the proposal with the applicant and a plan of action will be
agreed upon.
(3) The applicant will then prepare an application, in the format of a letter, addressed to
the local FSDO. Attach all pertinent data. The data should include:
(a) A clear description of the alteration.
(b) Drawings, sketches, or photographs, if necessary.
(c) Information such as thread size, stitch, pattern, materials used, and location of
altered components.
(d) Some means of identifying the altered parachute (model and serial number).
(4) When satisfied, the inspector will indicate approval by date stamping, signing, and
placing the FSDO identification stamp on the letter of application.
(5) Alterations to approved parachutes may be performed only by a certificated and
appropriately rated master parachute rigger, a current manufacturer of approved parachute
systems or components, or any other manufacturer the Administrator considers competent.
17. MATERIALS USED FOR REPAIRS TO APPROVED (TSO-APPROVED)
COMPONENTS.
a. Material Quality. Materials used for repairs to TSO-approved components, including
but not limited to fabric, suspension line, tape, webbing, thread, and hardware, must meet the
same specifications, requirements, and certifications of the original materials used by the
manufacturer.
b. Parachute Fittings. Hardware may be reconditioned and reused, as long as it complies
with subparagraph a. However, the plating or re-plating of load-carrying parachute fittings may
cause hydrogen embrittlement and subsequent failure under stress unless the plating is done
properly. Chrome or nickel-plated harness adjustment hardware may also have a smoother finish
than the original and may permit slippage.

APPENDIX 2. OPERATION OF AIRCRAFT WITH DOOR OFF OR MODIFIED FOR
PARACHUTING OPERATIONS
1. Operating Limitations Revision. The previous revision, Advisory Circular (AC) 105-2C,
Sport Parachute Jumping, Appendix 2, provided a list of aircraft that have FAA-approved door
open or removal procedure authorization with operating limitations. That list did not include all
the aircraft currently used in skydiving operations. Instead of continuing with the use of that list,
contact your local Flight Standards District Office (FSDO) for information on getting an
authorization to operate your aircraft with the door removed and/or a door modified to
open/close in flight. Aircraft that have approved procedure and operating limitations in their
FAA-approved Aircraft Flight Manual (AFM) or an FAA-approved Supplemental Type
Certificate (STC) may operate in accordance with those documents.
2. Operation with Modified or Removed Door. Any aircraft type, utility/normal category
model, that has had FAA-approved data used for skydiving operations or door removal can be
considered. It is the responsibility of the applicant to supply the FAA aviation safety inspector
(ASI) with any data necessary to have his or her aircraft approved to operate with a door
removed or a door modified to open/close in flight during jump operations. If the aircraft is
altered and operated in accordance with an STC, no other limitations are required.
NOTE: Many aircraft have jump door and/or restraint systems approved by
type certificate (TC), STC, or field approval. Aircraft that have not been
FAA-approved by TC, STC, or field approval must have the required data to
address the alteration from a Designated Engineering Representative (DER),
Organization Designation Authority (ODA), or other FAA-approved data.
This data will allow the owner/operator the ability to apply for a field
approval or one-time STC for that aircraft.
3. Previously Approved Field Approvals. A previously FAA-approved field approval for
jump door, handles, step, and skydiver restraint systems can be presented as data for the field
approval process if the FAA-approved data are for the same aircraft make, model, and series
(M/M/S).
4. Field Approval Process. Applicants need to follow the latest guidance found in FAA
Order 8900.1, Flight Standards Information Management System (FSIMS), Volume 4,
Chapter 9, Selected Field Approvals, for a field approval process. This guidance can be
referenced at http://fsims.faa.gov. Any changes to the flight manual require FAA and Aircraft
Certification Office (ACO) approval. Placards and skydiver restraint systems must be included in
the continued airworthiness instructions covering the repair of placards, restraint system
components, steps, handles, jump doors, etc. Installation, removal, and inspection of installed
equipment will be entered in the aircraft maintenance records, including the inspection checklist
for the installation and operational check of restraint systems. All aircraft used in skydive
operations will maintain records of all required FAA inspections and/or maintenance programs.
NOTE: For information regarding specific aircraft modified for skydiving
operations or STCs, contact the United States Parachute Association (USPA)

Appendix 3
APPENDIX 3. SEATS AND RESTRAINT SYSTEMS
1. Seating Configuration and Restraint System Safety. Not all seating and restraint system
configurations used in jump aircraft provide the same level of safety in the event of an
emergency landing. This appendix provides general information concerning the relative safety of
commonly used seating configurations and restraint systems. These safety assessments are based
on available research data and in-service experience.
2. General Information.
a. Quick Release Track Fittings. Single stud quick release track fittings have been shown
to release from the track at dynamic loads much lower than their rated strength. Dual stud quick
release fittings did not exhibit this behavior in dynamic tests. Therefore, dual stud quick release
fittings of the type shown in Figure 1 provide a much more reliable restraint anchorage than
single stud fittings.
b. Lap Belts. Lap belts are only effective if there is a solid support surface behind the
occupant, such as a seat back, aircraft sidewall, or bulkhead. Otherwise, a tether restraint that
attaches to the parachute harness provides more effective restraint.
c. Restraint for Aft-Facing Parachutists. Research has shown that to restrain aft-facing
parachutists, the most effective point to attach a tether restraint to a parachute harness is at the
junction of the leg straps, main lift web, and the horizontal back strap. Figure 2 illustrates this
attachment method, in which the tether loop encircles the junction by passing between the main
lift web and the horizontal back strap, and between the upper leg strap and the lower leg strap.
One way to achieve this is to route the tether loop under the upper leg strap, then under the main
lift web before latching the loop, as depicted in Figures 3 through 5. Since these two components
of the harness are easily assessable by the wearer, this attachment method should not be prone to
misuse. It also provides more effective restraint than attaching at other points on the parachute
harness since the restraining force is applied near the seated occupant’s center of gravity (CG).
d. Restraint Belts or Tethers. Past experience and testing have shown the validity of
attaching a restraint belt(s) or tether(s) to the parachute harness as part of the overall integrated
restraint system. However, most if not all parachute harness configurations have not been tested
to accept the load vectors that would be experienced during the actual use of this type of restraint
configuration.
•
•
Because of this, any parachute harness that has been subjected to actual use as part of
an integrated restraint system must be removed from service and inspected by the
manufacturer or a parachute rigger designated by the manufacturer to determine the
continued airworthiness of the parachute harness.
If the inspection shows that the harness is Airworthy, it may be returned to service.
3. Specific Seating/Restraint Configuration Information.
a. Side-Facing. Conventional side-facing bench seats employing dual point lap belts are a
superior means of carrying parachutists in aircraft large enough to accommodate them. They
Page 1
AC 105-2D
Appendix 3
5/18/11
offer the advantages of being simple to use and can be designed to provide significant vertical
energy absorption.
b. Rear-Facing Floor Seating.
(1) Restraints are more effective if attached to the floor instead of the sidewall. Only use
sidewall attachments if floor attach points are not available.
(2) Effectiveness is increased if overall tether length is kept as short as possible, and the
tether attachment to the aircraft is aft of the harness attachment point.
(3) Single point, single tether restraints are not very effective.
(4) Dual point, dual tether restraints offer superior restraint compared to single point,
single tether restraints. This restraint method consist of two straps, each connecting the parachute
harness to the aircraft floor on both sides of the parachutist as shown in Figures 6, 7, and 8.
c. Rear-Facing on Straddle Bench.
(1) Straddle benches can offer more occupant crash protection than floor seating since
they can be designed to provide significant vertical energy absorption.
(2) As with floor seating, restraints are more effective if attached to the floor instead of
the sidewall.
(3) Restraint effectiveness is improved if the tether strap is attached to the floor such that
it is at an approximately 45-degree angle, as shown in Figure 8.
(4) Single point, single tether restraints are not very effective.
(5) Dual point, dual tether restraints offer superior restraint compared to single point,
single tether restraints.
